    Increasing diesel engine power

    Well, its seems like its a case of mainly under fueling. A quick adjustment to the fuel delivery made a world of difference. I say mainly because it still has the same symptoms but much milder. Before it would get quite sluggish, now its just a slight power drop. Its noticeable if looking for it...

    Increasing diesel engine power

    Compositepro, No worries. I don't think you're being pedantic. More that I wasn't clear in what I wrote. It wasn't a doubling of the temp in DegC I was using to get that figure, I found that error earlier when I forgot to convert to Kelvin in my quick spreadsheet to get me a rough idea and...

    Increasing diesel engine power

    Will try to do that this weekend. We're having guests over so I'll see if he minds following me. Good to see the reputation of the courier engine is going strong, 1M45 km, thats some mileage! I don't understand why there would be power loss as it warms up if it was under fueled. Shouldn't it...

    Increasing diesel engine power

    Like this one? http://www.stealth316.com/2-turbotemp.htm With my turbo data plugged in I get about 156DegC at the outlet of the turbo with no heat absorption of the ambient air while passing in the engine bay. Probably already high enough to cause the effects I'm seeing. Add 4 feet of internal...

    Increasing diesel engine power

    Oh, forgot to answer your question. There is no smoke at all that I can notice.

    Increasing diesel engine power

    Thanks for the link winnyblue. I did actually know that which is one reason why I suspect that cooling the intake before the turbo would lower the outlet more effectively than cooling after the turbo. The Courier intercooler is known for being a bit on the small side but it is mounted outside in...

    Increasing diesel engine power

    Its a rebadged Mazda Bravo. The name is a Ford Courier. Mine is a twin cab ute (pickup). IIRC in the US and Europe it was called the Ford Ranger but the US version didn't have a diesel option. Later ones, 2003 IIRC went to direct injection so I have the a near last of the run of the old type...

    Increasing diesel engine power

    Its an indirect injection diesel, no fancy electronics at all. Very basic, no EGR or anything else. The closest thing is a PCV but I can't see how that would affect it to suit the observations. I'll build up some temp sensors and measure the variation at different points while driving to find...

    Increasing diesel engine power

    "As others have suggested, it depends on the actual temperature differentials between the intake air charge in the air duct after the inter cooler and the air in the under bonnet area it runs through." OK, I'm a bit confused here. The run from the inter-cooler to the inlet manifold is short. I...

    Increasing diesel engine power

    Clarification. Its about 4 feet prior to the turbo and about the same after, making about 8 total. Though this is a very rough guess.

    Increasing diesel engine power

    Its a 2002 Ford Courier (Mazda Bravo) with a 2.5L TD. I wish the piping was short and cylindrical, its however various shapes and quite long inside the engine bay. Rough guess would be about 4 feet inside the engine bay and part of it is a pipe about an inch high and four wide with lots of...

    Increasing diesel engine power

    I've noticed that in hot weather I get less power out of my engine and also I get less power out of it when it warms up fully. I'm guessing that this is because the intake air heats up so I have less air density. My car has a turbo and an inter-cooler, more correctly an after-cooler. I just...
